'is a side elevation of my invention as ap-` plied to a carding machine, certain parts of the latte? eing conventionally shown. Fig. 2 is asectional view, said section being taken in a plane parallel to the `plane of Fig. 1 and being diagrammatic in character. Fig. 3 is an end view of certain of the parts shown in Fig. 1, said view being also partly in section.

1 represents the surface of the main cylinder which is provided with the usual card clothing.

2--2 represent the so-called flats.

3 represents thellickerin roll of the ordinary type. f

4 represents the feed roll.

5 represents the lap roll.

6-6 represent mote knives.

7 represents stock being fed from the lap roll to the lickerin 3. The lickerin is provided with a saw-tooth surface of the usual r type. The adjacent surfaces of the main varied as particular conditions require.

The surface of the stripping cylinder 8 is Well removed from t-he surface of the main cylinder 1 and has no cooperation therewith.

11 is what I will term a stripping comb which is associated withthe surface of the stripping cylinder 8. This comb 11 is mounted u on a bracket 1Q, carried by a4 centric 16, which is mountedto loosely ro` tate, for example, upon an extension of the shaft 10.

17 is a pulley connected with the ec- P65 centric 16. y

18 is a drive belt leading from the pullev 17 to a drive pulley 19 on the main shaft (ir arbor of the main cylinder 1, hence, as the main cylinder 1 is rotated, it will drive the eccentric 1G, and, through the connections described, will operate the comb 11 toward and from the surface 0 of the stripping cylinder. The stripping cylinder 8L is driven in any suitable manner, preferably by a sprocket chain 90 leading from a sprocket 2lto a sprocket fixed on the shaft 10. The sprocket 21 is driven from any suitable source of power, but the same is preferably so associated with the feed of the machine that the relative speed of rotation of the cylinder 8 will be maintained. To accomplish this, the sprocket 21 might be mounted upon one of the shafts of the feed rolls, or the gears connected therewith, as shown diagrammatically in Fig. 1.

23 is a waste shaft of the ordinary type arranged to catch and collect waste, saidl shaft being driven, for example, by a sprocket.

In operation it is important to appreciate that the surface speed of the lickerin roll 3 and the stripping cylinder 8 is very materially different.V F or'example, in ordinary practice, the surface speed of the lickerin roll 3 would be approximately one thousand feet per minute, whereas the surface speed of the stripping cylinder 8 would be, for example, fifteen inches per minute, although these speeds may be varied within reason- 100 able ranges to increase or decrease the percentage of Waste being made and according to the quality of work desired and stock employed. It is also important to apl'ireriale that'the adjacent surfaces of the lickerin 105 roll andthe stripping cylinder move in the same direction. although at different speeds,

as above described.

IVhen the machine is in operation, the stock 7 is fed to the liekern 3 where it is 110 caught by the surface and carried rapidly forward toward the cylinder 1 in the direction of the arrows. On its forward vcourse of travel the stock passes the mote knives 6 which perform their usual function, after which it passes the adjacent surface 9 of the stripping cylinder 8, at which point a combing action takes place, the short fibers and other foreign substances being thrown on the stripping cylinder by centrifugal action, while the long fibers are held by the teeth of the lickerin and carried forward to the main carding cylinder 1. As the short fibers and foreign substances are accumulated upon the surface of the stripping cylinder 8, the surface of said cylinder moves forwardly, that is, in the direction of the arrows, Fig. 2, until said shortfibers and foreign substances encounter the comb 11, by whichv the same are removed from the surface and discarded. j

The surface speed'of the cylinder 8 and i the oscillating movement of the comb 11 are relatively such that although the comb moves to and fro, it will not be away from the surface 9 of the stripping cylinder -for a suflicient length of time at any period to permit vsaid waste-'or impurities to escape the action of the comb.- I have found in prac tice that by removing, so far as possible, the short fibers and other foreign substances from the stock upon the lickerin that the main cylinderand flats are not only kept in a cleaner and better condition, but that a superior quality of product is obtained than obtainableV by any machines as heretousual lickerin screen. Not on y is my iniy. the ordinary machine referred to in the reclaiming of cotproved machine superior 'to ton waste, but the actual product derived by employing my machine for this purpose ,is 'shown to be very much superior.

What I claim is: 1. In a carding machine, a main carding cylinder, a lickerlin roll adjacent thereto, the

adjacent surfaces of said cylinder and roll moving in the same direction, the former at a greater speed, a stripping cylinder having card clothing thereon, the surface yof said stripping cylinder being arranged vclosely adjacent to said lickerin roll, the adjacent surfaces of said roll and said strippingaaylL inder moving in the same direction, the latter at a very muchslower speed, and means for removing impurities and short fibers from the` card surface of said stripping cylinder.

2. In a carding machine, a main carding cylinder, a lickerinl roll adjacent thereto, the adjacent surfaces of said cylinder'and roll moving in the same direction, the former at a greater speed, a stripping cylinder having card clothing thereon, the surface of said stripping cylinder being Varranged closely adjacent to said lickerin roll, the adjacent surfaces of said roll and said stripping cylinder moving in the same direction, the latter at a very much slower speed, and means for removing impurities and short fibers from the card surface of said stripping cylinder, said cleaning means comprlsmg a comb.

3. In a carding machine, a main carding cylinder, a lickerin roll adjacent thereto, the

adjacent surfaces of said cylinder and roll `moving in the same direction, the former at a greater speed, a stripping cylinder having card clothing thereon, the surface o f said adjacent to said lickerin roll, the adjacent surfaces of said roll and said stripping cylinder moving inthe same direction, the latter at a very much slower speed, means for lstripping cylinder being arranged closely I removing impurities and short 4fibers from the card surface of said stripping cylinder,

said means 'comprisin a-comb, anda movable ,support for sai comb whereby said comb maybe moved to and fro inthe act' of removing said impurities from the card sur.

face of said stripping cylinder.
